It's not hard to see why polyurethane is so popular in outdoor projects. In this article, you'll learn about different types, including Wipe-on polyurethane, Oil-based polyurethane, and naphtha-based polyurethane. Furthermore, you'll learn how a brush can be used to apply the finish to prevent drips and streaks. You should be aware that polyurethane can have some disadvantages. This is something homeowners need to consider before choosing the finish.
Oil-based polyurethane
Make sure you clean the surface completely with mineral oil, alcohol, and a spray of polyurethane before applying it. Wiping the surface removes any air bubbles. Generally, water-based polyurethanes require three to four coats of polyurethane to achieve a satisfactory finish. Apply a thin coating of polyurethane in order to reduce the chance of bubbles. Apply a thin coat of polyurethane to the surface. Wipe it clean with a dry cloth or mineral spirit.
Use polyurethane wipe-on
A wipe-on finish polyurethane can be used in place of oil-based branded finishes. This type of finish has a good water resistance and scuff resistance. Wiping polyurethane without the need for high-end spray booths is an economical option. It can also be applied without the use a brush. Apply wipe-on plastic by thinning it with mineral spirits. Oil-based poly can be mixed 1:1 with mineral spirits, and wipe-on poly can be purchased pre-mixed.
Polyurethane thinned with naphtha
Protective gear is recommended before you begin the process of dipping your brush or rag in a bucket of polyurethane. High concentrations of mineral spirits can cause irritation to the skin. Thinners for thinning Polyurethane should not be used again. When handling thinners, gloves are recommended. Adding more of the substance will not accelerate the drying process.
Apply it using a brush
When applying polyurethane, two basic methods are recommended: brush on and wipe on. While brush on provides the best protection, with minimal buildup or drips, it is easier to wipe on without using brushes. Brush-on finishes dry in about four to six hour. The application process is easy. Wipe-on finishes require more coats but they are a better choice if you have stair balusters or small, flat areas.
Drying Time
The drying time for finishing polyurethane depends on several factors. Apply the coating on warm days to get the best results. This can be avoided by sanding the coat again and applying it again. The coating can crack if it is applied in extremely hot temperatures. If you're using oil-based polyurethane, ensure that you're working in a temperature that is no higher than 70degF or 21degC.

How To
How to stain hardwood
The process of staining wood involves the application of chemicals to the wood's surface, which causes it to change its color. This chemical reaction causes wood to turn from whiteish to brownish. Oak is the most commonly used wood for staining, but other woods can also be stained.
There are many methods to apply stain to wood surfaces. Mixing the stain in a solvent such as turpentine and spraying it onto the wood is one method. Some methods involve a mixture of water and dye that is applied directly to the wood. Stains can also be mixed into paints and varnishes, becoming part of the finish coating.
Preparing the surface for staining wood is the first step. The wood must be thoroughly cleaned to remove all grease and dirt. Sanding the wood removes scratches and imperfections. The next step is to choose the stain type you want. There are two basic kinds of stains: penetrating stains and non-penetrating stains. Penetrating stain penetrates deeper into wood than nonpenetrating, making them suitable for dark colors like mahogany. Light colors such as maple work well with non-penetrating stain.
After you've decided what type of stain to apply, get ready for your tools. Paintbrushes are great for applying stain because they allow you to evenly spread the liquid across the surface. After you're done painting, make sure to have some rags handy to remove any excess stain. If you plan on mixing the stain yourself make sure that you have enough containers to hold the different components.
Once you have prepared your materials, start by cleaning the area where you plan to stain the wood. Use warm water and soap to clean away dirt and dust. Wipe down all furniture pieces with a dampened cloth and clean water. If you intend to stain darker wood, make sure you get rid of any debris.
The stain should be applied next. Start at one end of the piece of furniture and brush or spray the stain onto the wood. Slowly and carefully move along the grain of wood, slowly but steadily, until you reach the other end. Keep the stain from dripping off the wood's surface. Let the stain dry completely before proceeding with the next steps.
Clear polyurethane is used to protect the painted surfaces. Apply three coats polyurethane sealer. Allow the third coat to dry overnight, before sanding.
